Thanks for signing up to use SigmaOS. These terms (Terms) apply to:

In these Terms, we sometimes refer to SigmaOS and the Software together as the "Services".

We are SigmaOS Software Limited. Our registered office is: ABBEY HOUSE SIGMAOS INC, 74-76 SAINT JOHN ST, LONDON, EC1M 4DT and we are registered in England and Wales under company number 13201691.

You can contact us by email at hello@sigmaos.com

Before you can start using SigmaOS, you'll need to create an account. To create an account, we'll need your name and email address. If you've signed in to SigmaOS via a third party login provider (like Apple ID), then we might be able to get some of this information from them.

When you accept these Terms we'll grant you a licence to use our Services. This license is non-exclusive (meaning we can grant the same licence to all users of our Services) and it's personal to you only (meaning you can't transfer the licence to anyone else).

When you accept these Terms, you agree not to:

You must be at least 13 years of age to use the Services. By using the Services you warrant and represent that you are at least 13 years of age. We may, but have no obligation to, monitor and review new accounts before you may sign in and start using the Services. Providing false contact information of any kind may result in the termination of your account.

We'll do our best to keep you up to date when we're making changes to our Services. We can change, update, pause, or discontinue any of our product features at any time. We don't need to give you any notice beforehand, but we'll try to be reasonable and let you know when we can.

When we say "Intellectual Property Rights", we mean any patents, copyrights, moral rights, trademarks, business names, domain names, designs, software rights, or confidential information that we hold. We also mean any other intellectual property rights (registered or not registered) that we hold now, or will hold in the future.

We and our licensors own all of the Intellectual Property Rights to our Services, and these Terms don't give you any of these rights.

In the future, we might transfer the rights and obligations we have under these Terms to another company, as long as it doesn't materially affect your rights. You can't transfer your rights or obligations under these Terms to anybody else. This is because these Terms are personal to you — and nobody else is entitled to benefit from them.

As we grow and improve SigmaOS, from time to time, we might need to make changes to these Terms.

Sometimes, when we release a new product feature or service, we might decide to introduce new terms relating to that feature. We might provide them separately to these Terms. If we do, you'll need to agree to those terms before you can use the feature.

If you carry on using our Services after we make changes to the Terms, it means you've agreed to them. The new version of the Terms replaces the old version — so the new Terms apply going forward.

Some parts of the Service are made available on a paid subscription basis ("Subscription(s)"). Pricing and included features for the Subscriptions (“Subscription Plan(s)”) are set forth here: https://sigmaos.com/. “Subscription Fees” means all fees associated with your Subscription.

You will be billed in advance on a recurring and periodic basis ("Billing Cycle"). Billing Cycles are set on a monthly or yearly basis. Whether you are using monthly or yearly billing, your account may be charged on a monthly basis.

Auto-Renewal: You agree that at the end of each Billing Cycle, your Subscription will automatically renew and your payment method for such Subscription will automatically be charged at the start of each new Subscription period for the fees and taxes applicable to that Billing Cycle, under the same conditions as the prior Billing Cycle unless you cancel your Subscription prior to your renewal date.

A valid payment method, including credit card, is required to process the payment for your Subscription. You must provide SigmaOS with accurate and complete billing information including full name, address, state, zip code, and valid payment method information. By submitting such payment information, you automatically authorize SigmaOS to charge all Subscription Fees incurred through your account to any such payment instruments.

Should automatic billing fail to occur for any reason, SigmaOS may attempt to charge the credit card on file one or more times. Should payment continue to fail, the Subscription will be, at SigmaOS’s sole discretion, canceled or downgraded and you may lose access to certain paid features and/or your Workspace and SigmaOS account.

You may cancel your Subscription either through your online account management page or by contacting SigmaOS team at hello@sigmaos.com and indicating your intention to cancel your Subscription.

SigmaOS offers an AI feature, Airis, which leverages OpenAI's ChatGPT technology to enrich your browsing experience. Airis, activated on user request, interacts with the plain text visible on your current webpage. No cookies, extensions, preferences, or passwords are ever transmitted. However, if personal data is visible in plain text and Airis is engaged, it may be included in the context sent to OpenAI. Please exercise discretion when using this feature.

Data sent to the OpenAI API is anonymized and can't be traced back to individual users, as it's chunked together and sent from SigmaOS without any direct link to your user account or ID. Data retention complies with OpenAI's standard policies, which you can review in OpenAI's privacy policy.

Using Airis is entirely voluntary. Data will only be transmitted to OpenAI if you actively engage the feature. By using Airis, you agree to these terms and our Privacy Policy.

SigmaOS, in its sole discretion and at any time, may modify the Subscription Fees for the Subscriptions. Any Subscription Fee change will become effective at the end of the then-current Billing Cycle.

SigmaOS will provide you with reasonable prior notice of any change in Subscription Fees. Your continued use of the Service constitutes your agreement to pay the modified Subscription Fees.

Subscription Fees are stated exclusive of any taxes or similar governmental assessments of any nature, including, for example, value-added, sales, use or withholding taxes, assessable by any jurisdiction (collectively, “Taxes”). You will be responsible for paying all Taxes associated with your Subscription, except for those taxes based on our net income. Should any payment for the Service be subject to withholding tax by any government, you will reimburse us for such withholding tax.

SigmaOS may, at its sole discretion, offer a Subscription with a free trial for a limited period of time ("Free Trial"). If you are on a Free Trial, you may cancel at any time until the last day of your Free Trial by following the cancellation procedures outlined in the Subscription section of these Terms. If you or SigmaOS cancel your Free Trial, you acknowledge and agree that we may delete all of your User Content or data associated with the Workspaces that was assigned to your Free Trial. If you do not cancel your Free Trial, then your Free Trial will be converted to a paid Subscription at the end of the trial period, and you hereby authorize us to charge your credit card or other payment method for continued use of the paid Service under such Subscription.

At any time and without notice, SigmaOS reserves the right to (a) modify the terms and conditions of any Free Trial offer; (b) cancel any Free Trial offer; or (c) cancel any Free Trial subscription at any time.

14-day money-back guarantee: if you decide you no longer wish to use or retain access to the services to which you've subscribed and paid for, you may contact us via emailing hello@sigmaos.com to request cancellation within 30 days of the original purchase to receive a refund. This only applies to first-time purchases for new users.

All other payment obligations are non-cancelable, and fees paid are non-refundable and there are no credits for partially used Subscription periods.

If you don't follow the Terms we've set out, we can remove your access to SigmaOS straight away. This means that you'll no longer be able to access your account, and you won't be allowed to open a new account in the future.

We can also remove your access to all or parts of SigmaOS without giving you a reason. If we want to do this, we'll provide you with at least 30 days' notice. From time to time, we might need or choose to impose limits on our Services. If we do, we'll try to give you 30 days' notice.

While we hope you'll love using SigmaOS, we can't guarantee that it'll meet your needs. We also don't guarantee that the service will always be available, or be free from errors. From time to time, it's possible that your access to the service will be interrupted. If this happens, we won't be responsible for any loss or damage that comes about as a result.

We take steps to preserve your data, and protect its integrity. We won't be responsible for loss of your data, or any corruption to it.

If you run into problems using SigmaOS — we can help. You can contact us via our Community Slack channel, or email us on hello@sigmaos.com.

To keep SigmaOS safe and running smoothly, we keep an eye on how people are using our Services, and take action when we need to. You agree that we can monitor your use of SigmaOS to make sure you're not breaking our Terms. We'll always do this in line with our privacy policy.

To learn more about how we'll use your personal information, please read our privacy policy.

These Terms are governed by English law and the English courts will have jurisdiction over any claim. If you're a resident outside of the UK, then you'll continue to have all of the consumer rights available to you in your country of residence.
